Questions and answers

What the research says

• Preoperative treatment with benzoyl peroxide significantly decreases the bacterial skin load of Cutibacterium acnes in patients undergoing elective shoulder surgery from skin incision until wound closure compared to preparation with soap.

  Journal of Shoulder and Elbow Surgery, 2021

• Topical benzoyl peroxide may improve acne more effectively than placebo or no treatment, while showing little to no difference compared with adapalene or clindamycin, but with an increased risk of treatment discontinuation due to adverse effects compared to placebo.

  The Cochrane Database of Systematic Reviews, 2020

• Once-daily fixed-dose clindamycin phosphate 1.2%/benzoyl peroxide 3.1%/adapalene 0.15% gel achieved superior treatment success (52.5%) and greater reductions in inflammatory and noninflammatory lesions compared to vehicle (8.1%) and dyad component gels in participants with moderate-to-severe acne over 12 weeks.

  American Journal of Clinical Dermatology, 2022

• Pranoprofen-loaded nanostructured lipid carriers dispersed in Carbomer 940 and Sepigel 305 gels provided sustained drug release and demonstrated anti-inflammatory efficacy in animal models without causing skin irritation or altering biophysical properties in humans.

  Gels, 2023

• Twice daily application of a multitargeted dermocosmetic cream provided comparable efficacy to benzoyl peroxide 5% gel in reducing inflammatory, non-inflammatory, and total lesions in 150 Caucasian subjects with mild-to-moderate acne over 56 days, while demonstrating superior skin tolerability.

  Journal of Cosmetic Dermatology, 2024

• Topical clindamycin phosphate 1.2%/adapalene 0.15%/benzoyl peroxide 3.1% gel achieved significantly greater treatment success and lesion reductions compared to vehicle in participants with moderate-to-severe acne.

  Journal of the American Academy of Dermatology, 2023

• Daily application of adapalene 0.3%/benzoyl peroxide 2.5% gel reduced and prevented atrophic acne scar formation, achieving a total scar count change of -15.5% versus +14.4% for vehicle over 24 weeks in 67 subjects with moderate or severe facial acne.

  American Journal of Clinical Dermatology, 2018

• Topical chloramphenicol-betamethasone combined with sodium hyaluronate/trehalose/carbomer gel compared to chloramphenicol-betamethasone alone reduced most subjective symptoms at 1 week but increased blurred vision at 4 weeks following strabismus surgery in 31 patients, with no significant differences in conjunctival inflammation between treatments.

  Journal of Ocular Pharmacology and Therapeutics, 2019

• Incorporating nanoemulsions into hydrogels with increasing Carbopol 934 proportions from 1% to 3% progressively decreased the percutaneous flux rates of terbinafine and citral, increased drug accumulation in the stratum corneum while decreasing it in the epidermis/dermis compared to nanoemulsions alone, and shifted delivery routes from skin appendages to intercellular paths.

  International Journal of Nanomedicine, 2016

• Topical liquiritin carbomer gel treatment restored skin barrier function, increased barrier proteins and antioxidant enzymes, and decreased inflammatory cytokines and oxidative stress in a mouse model of glucocorticoid-induced skin inflammation.

  Pharmaceutics, 2024

• A single application of a moisturizing fluid containing hyaluronic acid 1%, glycerin 5%, and Centella asiatica stem cells extract significantly increased skin hydration by 29% and reduced transepidermal water loss at 24 hours compared to baseline and an untreated control site in twenty healthy women.

  Clinical, Cosmetic and Investigational Dermatology, 2017

• The emollient V0034CR significantly reduced TEWL compared to vehicle and vehicle plus glycerol, and significantly increased corneometry scores compared to vehicle and vehicle plus petrolatum in healthy volunteers with dry skin, demonstrating combined barrier function improvement from petrolatum and hydration improvement from glycerol.

  Journal of Cosmetic Dermatology, 2020

• Ten days of treatment with a cream containing 20% glycerin significantly increased skin hydration measured by corneometer values in 17 healthy volunteers compared to a placebo cream, but showed no influence on transepidermal water loss or skin sensitivity to an irritating surfactant.

  International Journal of Cosmetic Science, 2001

• A functional cosmetic cream containing bioactive materials from Streptomyces sp. T65 embedded in SBA-15 decreased skin roughness by 4.670% and increased skin brightness by 0.472% after 4 weeks of application, while demonstrating antimicrobial, antioxidant, anti-aging, and whitening activities.

  Antioxidants, 2020

• Film-forming formulations containing porous silica achieved skin permeation rates comparable to immediate release formulations while confirming prolonged drug availability and causing no skin irritation in healthy volunteers.

  European Journal of Pharmaceutical Sciences, 2017

• Topical treatment with silica mud and microalgae extracts from the Blue Lagoon improved skin barrier function by inducing epidermal gene expression and reducing transepidermal water loss in healthy humans, while preventing skin aging markers in vitro.
